Summary
You'd reach for this when you need persistent memory across agent sessions. It bundles vector storage for semantic search, recall mechanisms to retrieve past context, summarization to compress conversation history, and redaction tools to scrub sensitive data. The ten tools cover the full lifecycle of agent memory management, from storing embeddings to pulling relevant context back when needed. Useful if you're building agents that need to remember previous interactions or maintain knowledge bases that grow over time. The streamable HTTP transport means you can integrate it remotely without running the server locally.

Persistent long-term memory for AI agents. Agents never forget.
10 tools. SQLite FTS5 full-text search. Per-namespace isolation. GDPR-compliant forget. Cross-references with FeedOracle Trust Layer.

The problem
Every MCP tool call is stateless. When Claude Desktop restarts, when Cursor closes, when the session ends — the agent forgets everything. No user preferences, no project history, no learned rules, no portfolio tracking.
MemoryOracle gives agents a persistent, searchable memory that survives restarts, works across clients, and gets more valuable over time.
Tools
| Tool | What it does |
|---|---|
store_memory | Store a fact, preference, decision, or rule. Deduplicates automatically. |
query_memory | Full-text search with BM25 ranking and recency boost |
update_fact | Update a memory with new info. Preserves version history (last 10 changes) |
forget | Permanently delete by ID, category, age, or everything. GDPR Art. 17 |
summarize_session | End-of-session capture: summary + extracted facts, decisions, action items |
list_memories | Browse with filters: category, importance, recency, access frequency |
cross_reference | Verify a memory against FeedOracle Trust Layer evidence |
memory_stats | Dashboard: count, storage, categories, most accessed, recent |
export_memories | Export all as JSON. GDPR Art. 20 data portability |
health_check | Service status |
Memory categories
| Category | When to use |
|---|---|
fact | Verified information: "USDC is MiCA authorized" |
preference | User/agent preferences: "Conservative allocation, no USDT" |
decision | Decisions made: "Blocked USDT for EU clients" |
observation | Patterns noticed: "RLUSD peg stable for 30 days" |
rule | Business rules: "Never recommend assets with peg deviation > 2%" |
session | Session summaries with linked facts |
portfolio | Portfolio positions and allocations |
action_item | Open tasks: "Check RLUSD status in April" |
Example: Compliance agent workflow
Session 1 — Agent does MiCA compliance checks:
{"name": "store_memory", "arguments": {
"content": "USDT blocked for EU — MiCA NOT AUTHORIZED. Preflight: STOP.",
"category": "decision", "importance": 10,
"tags": ["usdt", "mica", "blocked"],
"namespace": "compliance-bot"
}}
Session 2 — Next day, agent remembers:
{"name": "query_memory", "arguments": {
"query": "USDT EU compliance status",
"namespace": "compliance-bot"
}}
→ Instantly recalls the decision from yesterday. No re-checking needed.
End of session — Auto-capture:
{"name": "summarize_session", "arguments": {
"summary": "Reviewed stablecoin portfolio. USDT blocked. RLUSD pending.",
"key_facts": ["USDC authorized", "EURC authorized", "USDT blocked"],
"decisions": ["Block USDT for EU"],
"action_items": ["Check RLUSD in April 2026"],
"namespace": "compliance-bot"
}}
Why this is different
| Feature | MemoryOracle | Others |
|---|---|---|
| Search | FTS5 BM25 ranking + recency boost | Basic keyword |
| Categories | 8 structured types | Flat key-value |
| Session capture | Auto-extracts facts, decisions, actions | Manual only |
| Trust Layer | Cross-reference with signed evidence | None |
| GDPR | Art. 17 forget + Art. 20 export | Usually missing |
| Namespaces | Per-agent isolation | Shared global |
| History | Version tracking (last 10 changes) | Overwrite |
| TTL | Auto-expiry with configurable hours | None |
